An ordinary summer's day. The grass is green, the flowers are blooming. All is right with the world. Then the dead start rising. From cemetery and mortuary, funeral home and morgue, they flood into the streets until every town and city is infested with walking corpses, blank-eyed eating machines that exist to take down the living. The world is a graveyard. And when you have a family to protect, it's more than survival. It's war.
